Master of Science / Department of Computing and Information Sciences / William H. Hsu / Pitch detection and instrument identification can be achieved with relatively high accuracy when considering monophonic signals in music; however, accurately classifying polyphonic signals in music remains an unsolved research problem. Pitch and instrument classification is a subset of Music Information Retrieval (MIR) and automatic music transcription, both having numerous research and real-world applications. Several areas of research are covered in this thesis, including the fast Fourier transform, onset detection, convolution, and filtering. Basic music theory and terms are also presented in order to explain the context and structure of data used. The focus of this thesis is on the representation of musical signals in the frequency domain. Polyphonic signals with many different voices and frequencies can be exceptionally complex. This thesis presents a new model for representing the spectral structure of polyphonic signals: Uniform MAx Gaussian Envelope (UMAGE). The new spectral envelope precisely approximates the distribution of frequency parts in the spectrum while still being resilient to oscillating rapidly (noise) and is able to generalize well without losing the representation of the original spectrum. When subjectively compared to other spectral envelope methods, such as the linear predictive coding envelope method and the cepstrum envelope method, UMAGE is able to model high order polyphonic signals without dropping partials (frequencies present in the signal). In other words, UMAGE is able to model a signal independent of the signal’s periodicity. The performance of UMAGE is evaluated both objectively and subjectively. It is shown that UMAGE is robust at modeling the distribution of frequencies in simple and complex polyphonic signals. Combined classification (combiners), a methodology for learning large concepts, is used to simplify the learning process and boost classification results. The output of each learner is then averaged to get the final result. UMAGE is less accurate when identifying pitches; however, it is able to achieve accuracy in identifying instrument groups on order-10 polyphonic signals (ten voices), which is competitive with the current state of the field.

This thesis deals with the polyphonic and argumentative functions of the French negation marker, ne, in editorial texts from the daily press. The concept ‘polyphony’ relates to the presence of multiple voices within one and the same utterance. According to this view, negation triggers a subdivision of an utterance in two points of view. Thus the sentence Sweden will not be a part of the monetary union can be divided in two points of view, the underlying ‘Sweden will be a part of the monetary union’, and the explicit ‘Sweden will not be a part of the monetary union’. First, I study the polyphonic structure of negative utterances, notably their division in two points of view, by taking into account their specific linguistic features. This is done so as to identify the relevant linguistic criteria that determine the polyphonic interpretation of the negation. The study demonstrates that contextual elements, including pragmatic connectors, presuppositions contrastive elements, and several other devices constitute the primary source of polyphonic markers. Negation is furthermore approached from a textual perspective. I explore how the two opposite points of view that are associated with negation form polyphonic sequences with other points of view carrying the same semantic content, and how these dynamic points of view are associated to the different discourse beings that are found in the newspaper article. I found that these sequences often embrace the central polemic theme of the article and, also, that the polyphonic function is not restricted to the negative utterance but constitutes an element that ensures textual and argumentative coherence. These two analyses are carried out within Jean-Claude Anscombre’s and Oswald Ducrot’s Theory of Structural Argumentation, which has recently been formalised by Kjersti Fløttum, Coco Norén and Henning Nølke. Finally in this thesis, I analyse the relation between the discourse beings associated with the negative utterance and real beings that exist outside the text, and then consider what rhetorical implications that correspondence or no correspondence has on the polyphonic interpretation of the negation. I also examine whether polyphonic negation can be considered to be a feature of newspaper editorials that identifies these texts as a genre. This study shows that the locuteur, the discourse being responsible for the enunciation of the negative utterance on a textual level, links to the real being, the editorial writer, who then refutes points of view associated to other discourse beings, often by use of nominalizations that refer to community voices. The locuteur also intrudes into an argument or claim, and refutes it in the name of a community or an authority. By defining genre, as does the media researcher Patrick Charaudeau, as a correspondence between the constraints imposed by the discursive situation and the constraints imposed by the discursive features, and by considering that one of the editorial’s constraints is to persuade its readers, this study shows that the phrasal negation ne in its polyphonic function, constitutes a distinguishing feature in the genre of editorials. The refutations that are made by an editor constitute a distinctive argumentative strategy since it permits the editorial writer to present external points of view in order to refute them and thereby impose his or her own, subjective point of view.

The thesis´ aim is to deepen the understanding about what shapes and characterises the purchase process for management advice services. Such externally, acquired services have increased substantially, and in relation to the services´ impact on management decisions the theoretical and practical understanding of the purchase process is lagging behind. The thesis´ analyses, interpretations and conclusions are founded on empirical data collected by use of focus groups, and based on activity theory. The findings show that the purchase process is influenced by many actors who see themselves as subject in the process. They have similar but also conflicting objects that they want to fulfil. The outcome of the purchase process is influenced by contradictory opinions among the actors about how to organize and supervise the process. The main contradictions are influenced by the actors´ different objects and how they interpret the context of the purchase process. The context is shaped by such as leadership style, social rules regarding management of change and opinions about division of labour in the purchase process. The impression of the purchase process´s character is that commonly used supply chain models do not work as a characterization. The purchase process´s phases do not follow on each other and the glue that links the phases is not a rational procedure following one, firm route. The findings show that procurement, integration and follow-up phases overlap, are concurrent and integrated in each other. The purchase process reproduces the execution of polyphonic music in which different voices, each with its own melody, create a rich texture of sounds. In a similar way the purchase process is coined by actors who bring their own objects and competence into the process. It produces dissonance, as in polyphonic music. It mirrors the services character of competence development and shapes the purchase process as polyphonic rather than a rational, step by step process.

The purpose of this thesis was to make available for performance and study an edition of the twenty-two secular songs published in this collection by Johann Jacob Löwe and Julius Johann Weiland in 1657. The thesis contains twenty-two secular songs for one, two, or three voices with continuo accompaniment and ritornellos for one or two violins, and/or viola, as well as translations of Lowe's preface and dedication and a poem to Lower and Weiland by Heinrich Schaffer. The work contains three chapters, the first covering Lowe's life and work and association with Weiland, the second the state of German secular song in 16050, and the third a critical commentary on the editing of the songs. Editorial corrections are included.

A proposta teórica fundamenta-se na enunciação, enfatizando a concepção polifônica de Ducrot que, aliada a conceitos oriundos da análise de discurso de Pêcheux, permite descrever os fatos de língua, perceptíveis no fio do discurso, e desenvolver a compreensão dos efeitos de sentido, produzidos pelo cruzamento entre o intradiscurso e o interdiscurso que se faz presente na seqüência lingüística, através do trabalho da memória. A análise compreende dois níveis. No primeiro, fazemos a descrição das marcas lingüísticas, que permitem identificar o locutor e os enunciadores com seus pontos de vista, estruturados no jogo polifônico da enunciação. No segundo, empreendemos a interpretação dos efeitos de sentido que se instituem no ponto de encontro entre a rede de sentidos impl / This study intends to identify which images of the Institution and of the addressee can be noticiable from the slogans of three advertising campaings of Universidade do Vale do Rio dos Sinos, located at the Metropolitan area of Porto Alegre, Rio Grande do Sul. It is based on the enunciation, emphasizing the polyphonic conception of Ducrot and the concepts of Pêcheux’s discourse analysis. This theoretic base allows to describe the facts of the language that are perceivable in the thread of the speech and it also allows to develop the comprehension of the sense effects that are taken by the intersection of the intradiscourse and the interdiscourse that is present in the linguistics sequency, throught memory action. The analysis includes two levels. First, the linguistics tracks, which allows to identify the speaker, and the announcer with their point of views structured in the polyphonic game of enunciation are described. Secondly, the sense effects that are established at the meeting point among the sense

Choro vadovo darbo profesionalumą atspindi tinkamas mokymo metodų parinkimas, mokėjimas juos derinti su menine, muzikine veikla ir tuo būdu pasiekti norimų ugdymo rezultatų. Todėl ugdant daugiabalsį dainavimą jaunių chore būtinas kryptingas bei sistemingas vadovo darbas. Paskelbti Lietuvoje tyrimai, dainavimo problematiką analizuojantys metodiniai leidiniai bei straipsniai iš esmės nesuformuluoja išsamaus ir esminio daugiabalsumo ugdymo metodų taikymo chore galimybių. Nefiksuojama, kokie pagrindiniai būdai turėtų būti taikomi šiam tikslui pasiekti. Vadovaujant jaunių chorui, tokia literatūra, kurioje nurodomi daugiabalsumo lavinimo pratimai be metodinių paaiškinimų, pedagoginiame darbe sukelia tik painiavos, o ne rezultatyvumo. / The managerial professionalism of the choir leader is reflected by the selection of appropriate teaching methods, the ability of combining them with the artistic and musical activities and thereby achieving the desired educational outcomes. Therefore, training polyphonic singing in the youth choir requires a systematic and purposeful leadership. Researches published in Lithuania, methodical publications and articles, analyzing singing problems practically do not formulate the opportunities of complete and essential polyphonic training techniques of the choir.
